Abstract

A doctor for a printing press having a rounded doctor profile (3) is distinguished by the fact that the radius of curvature of the doctor profile (3) is greater at the point (10) which corresponds to the doctor angle (α) than at a tangent point (11) which lies 20° further towards the tip and smaller than at a tangent point (12) which lies 15° further towards the flank.
